are. for more of granny's celebration, including the performances, as some are really worth taking a longer look, visit our blog at cnn.com/outfront. "ac 360" starts right now. erin, thanks. good evening, everyone, from newtown, connecticut. one month ago, tragedy touched down in his idyllic town, forever changing the lives of so many people here. one month later, the crowds, reporters, and law enforcement personnel are gone, but the pain for many families here remain. for the first time in the town hall behind me, family members of 11 victims of the tragedy had a conversation, about health, school safety, and what they call gun responsibility. you'll hear from a number of families tonight about how they're coping one month since they lost their son or daughter, their brother or their sister. much of the world may have moved on, but grief does not conform to any time table.
